- the TV control method 900is described below.
- the fingerprint identification module 182identifies a fingerprint of a specific user. For example, when the specific user “Neo” currently holds the remote controller 180 , in response to a touch from the specific user “Neo”, the fingerprint identification module 182 identifies the fingerprint of “Neo” and generates an ID data “a098fjkx” corresponding to “Neo”.
- the wireless module 184transmits an ID data of the specific user, and more particularly transmits a wireless signal carrying the ID data “a098fjkx” when the specific user is “Neo”.
- Step 922the user identification module 116 determines whether the current user is a valid user. More particularly, the user identification module 116 searches the database 114 according to the ID data received from the remote controller 180 , so as to determine whether the current user is the valid user. When the answer is yes, Step 924 is performed; otherwise, Step 928 is performed. For example, when the user identification module 116 searches the database 114 according to the ID data “098fjkx”, and determines that the ID data “098fjkx” corresponds to the user “Neo”, Step 924 is performed.
- the user identification module 116accesses channel selecting information. For example, the user identification module 116 retrieves channel selecting information corresponding to the specific user from the database 114 according to the ID data, and transmits the channel selecting information to the channel selecting module 118 .
- the channel selecting module 118selects a favorite channel of the user, and more particularly selects the favorite channel according to the channel selecting information of the specific user. For example, when the specific user is “Neo”, the channel selecting module 118 selects a channel according to a favorite channel (channel 5 in this embodiment) of the specific user “Neo”. According to this embodiment, channel selecting information of each of the users comprises a favorite channel. For example, when the channel selecting information from the latest statistics of the database 114 indicates the favorite channel of the user “Neo” is channel 5 , the channel selecting module 118 accordingly learns that the favorite channel of the user “Neo” is channel 5 and thus selects channel 5 .
- the channel selecting information of each usercomprises a favorite channel or a plurality of favorite channels each having a priority.
- the channel selecting module 118activates the TV receiver 110 to display the numbers of the favorite channels in the priority sequence so that the user can select one of the favorite channels.
- the channel selecting module 118when a reply of the user is not obtained within a predetermined time, e.g., several seconds, the channel selecting module 118 directly determines that a favorite channel having a highest priority, e.g., channel 5 , is the favorite channel.
- the channel selecting module 118selects a channel according to a common approach; however, this example is disclosed to gain a better understanding of the present invention, and it shall not be construed as limiting the present invention.
- the database 114further stores channel selecting information corresponding to a general user. Therefore, the channel selecting module 118 selects a channel according to the channel selecting information corresponding to the general user.
- FIG. 3is a flowchart of a TV control method in accordance with an embodiment of the present invention. More particularly, FIG. 3 is a flowchart of the control flow 930 of the TV receiver 110 , and this embodiment is a variation of the embodiment illustrated in FIG. 2 .
- channel selecting information of at least one usermay further comprise one or more channel prohibited from viewing.
- the user “Neo”is the head of a family, he has an authority for defining the TV system 100 , such as defining a prohibited channel with respect to each member of the family. In addition to defining a prohibited channel for an underage member, the user “Neo” may also define an unwished channel as a default prohibited channel for the entire family.
- Step 932the TV receiver 110 receives the wireless signal via the wireless module 112 to obtain the ID data of the specific user.
- the user identification module 116retrieves the channel selecting information corresponding to the specific user. More particularly, the user identification module 116 retrieves the channel selecting information corresponding to the specific user from the database 114 and provides the obtained channel selecting information to the channel selecting module 118 . For example, when the specific user is “Neo”, the user identification module 116 searches the database 114 for the ID data carried by the wireless signal, and accordingly retrieves the channel selecting information corresponding to the user “Neo”.
- Step 936after receiving the channel selecting information provided by the user identification module 116 , the channel selecting module 118 learns whether the channel selecting information comprises prohibited channels. More particularly, after receiving the channel selecting information provided by the user identification module 116 , the channel selecting module 118 learns whether the channel selecting information comprises a prohibited channel list. When the channel selecting information comprises prohibited channels, Step 938 - 1 is performed; otherwise, Step 938 - 2 is performed. For example, after Step 934 of retrieving the channel selecting information corresponding to the user “Neo” by the user identification module 116 and providing the channel selecting information to the channel selecting module 118 is performed, the channel selecting module 118 learns that the channel selecting information comprises prohibited channels 54 and 55 , and Step 938 - 1 is to be performed.
- Step 938 - 1the channel selecting module 118 selects a channel according to the channel selecting information and skips the prohibited channels during a channel switching. More particularly, when the user “Neo” activates the TV receiver 110 to select his favorite channels, under control of the channel selecting module 118 , Step 924 and Step 926 are performed. Once the user “Neo” switches channels one after another, channels 54 and 55 are skipped. For example, when switching from channel 40 and upwards, channel 53 directly jumps to channel 56 without going through channels 54 and 55 . When switching from channel 70 and downwards, channel 56 directly jumps to channel 53 without going through channels 55 and 54 .
- Step 938 - 2the channel selecting module 18 selects a channel according to the channel selecting information. For example, when the specific user activates the TV receiver 110 via the remote controller 180 to select his favorite channels, under control of the channel selecting module 118 . Step 924 and Step 926 are performed. Since no prohibited channel exists under this condition, once the specific user switches channels one after another, the channel is switched upwards and downwards in a normal numerical order.

Abstract
Description
- CROSS REFERENCE TO RELATED PATENT APPLICATION
- This patent application is based on Taiwan, R.O.C. patent application No. 098114962 filed on May 6, 2009.
- The present invention relates to a television (TV) control based on user habits, and more particularly, to a TV receiver, an associated system and a TV control method.
- In the prior art, a TV remote controller usually has a button for returning from a currently viewed channel to a previously viewed channel, and a user may also press the button to switch between the two channels. However, this simple design can not meet requirements of most users.
- More particularly, in order to immediately switch to a desired channel, the user has to memorize numbers of certain favorite channels. Yet, with respect to a user without a good memory, such prerequisite of memorizing the numbers of the favorite channels is inconvenient even to an extent of infeasible, such that the user is forced to continuously switch channels one after another to find a favorite channel. There are some remote controllers that provide other buttons to solve the foregoing problem. However, it is still impractical for a family having several members when each of the members has his own favorite channels.
- As mentioned above, the design of the prior art is too simple and the available solution is impractical to meet user requirements. Therefore, the conventional technology needs to be improved.
- One object of the present invention is to provide a TV receiver, an associated TV system, and a TV control method to solve the foregoing problem.

The wireless module receives a wireless signal carrying an identification (ID) data of a specific user. The database stores channel selecting information corresponding to a plurality of users. The user identification module retrieves channel selecting information of the specific user from the database according to the ID data of the specific user. The channel selecting module selects a channel according to the channel selecting information corresponding to the specific user.
- An associated TV system corresponding to the foregoing TV receiver is provided according to an embodiment of the present invention. The associated TV system comprises a remote controller, a wireless module, a database, a user identification module, and a channel selecting module. The remote controller transmits a wireless signal carrying an ID data of a specific user. The wireless module receives the wireless signal. The database stores channel selecting information corresponding to a plurality of users.

Theanalysis module 120 respectively gathers statistics on users' viewing habits, and in particular, with the aid of thechannel selecting module 118, counts the numbers of times of viewing respective channels by the respective users, so as to obtain a distribution of the numbers of times of viewing the channel. More specifically, when a user views a program, theanalysis module 120 learns an identity of the current user from theuser identification module 116, and gathers statistics on viewing habits of the user. In particular, from thechannel selecting module 118, theanalysis module 120 gathers and counts the numbers of times of viewing respective channels by the respective users, so as to obtain a distribution of the numbers of times of viewing the channel. Thus, corresponding to the users, theanalysis module 120 respectively generates channel selecting information to be stored into thedatabase 114. According to this embodiment, theanalysis module 120 updates the channel selecting information stored in thedatabase 114 at all times or on a predetermined schedule. In a preferred embodiment, theanalysis module 120 further gathers statistics on channels viewed by each user at different time points. - Upon detecting a touch from a specific user, the
remote controller 180 transmits an ID data of the specific user to theTV receiver 110. After having received the ID data, the TV receiver selects a corresponding channel, i.e. channel selection is performed. In this embodiment, the ID data comprises a data representing fingerprint information of the specific user. For example, the ID data is a group of 16-bit codes or a bit string. - For example, names of the users comprises “Neo”, “Trinity”, “Morris”, and “Bob”, fingerprint information of the users are respectively “a098fjkx”, “adsvk93”, “9839xkss”, and “akavkek2”, and supposing the specific user currently holding the
remote controller 180 is “Neo”. In response to a touch from “Neo”, thefingerprint identifying module 182 generates the ID data “098fjkx” of the specific user “Neo”, and thewireless module 184 correspondingly transmits a wireless signal including the ID data “098fjkx”. Thewireless module 112 of the TV receiver receives the wireless signal carrying the ID data “098fikx” of the specific user “Neo” from thewireless module 184. In addition, in response to the wireless signal received by thewireless module 112, theuser identification module 116 retrieves channel selecting information corresponding to the user “Neo” from thedatabase 114. Accordingly, thechannel selecting module 118 selects a corresponding channel. - According to this embodiment, the
wireless modules wireless module 184 is an infrared transmitting module, and thewireless module 112 is an infrared receiving module. However, this example is disclosed to gain a better understanding of the present invention, and it shall not be construed as limiting the present invention. According to a variation of this embodiment, thewireless modules wireless modules FIG. 2 is a schematic diagram illustrating steps of aTV control method 900 in accordance with an embodiment of the present invention. TheTV control method 900 is applied to theTV system 100 illustrated inFIG. 1 . TheTV control method 900 comprises acontrol flow 910 of a remote controller and acontrol flow 920 of a TV receiver, which respectively correspond to theremote controller 180 and theTV receiver 110 illustrated inFIG. 1 . TheTV control method 900 is described below.- In
Step 912, thefingerprint identification module 182 identifies a fingerprint of a specific user. For example, when the specific user “Neo” currently holds theremote controller 180, in response to a touch from the specific user “Neo”, thefingerprint identification module 182 identifies the fingerprint of “Neo” and generates an ID data “a098fjkx” corresponding to “Neo”. - In
Step 914, thewireless module 184 transmits an ID data of the specific user, and more particularly transmits a wireless signal carrying the ID data “a098fjkx” when the specific user is “Neo”. - In
Step 922, theuser identification module 116 determines whether the current user is a valid user. More particularly, theuser identification module 116 searches thedatabase 114 according to the ID data received from theremote controller 180, so as to determine whether the current user is the valid user. When the answer is yes,Step 924 is performed; otherwise,Step 928 is performed. For example, when theuser identification module 116 searches thedatabase 114 according to the ID data “098fjkx”, and determines that the ID data “098fjkx” corresponds to the user “Neo”,Step 924 is performed. - In
Step 924, theuser identification module 116 accesses channel selecting information. For example, theuser identification module 116 retrieves channel selecting information corresponding to the specific user from thedatabase 114 according to the ID data, and transmits the channel selecting information to thechannel selecting module 118. - In
Step 926, thechannel selecting module 118 selects a favorite channel of the user, and more particularly selects the favorite channel according to the channel selecting information of the specific user. For example, when the specific user is “Neo”, thechannel selecting module 118 selects a channel according to a favorite channel (channel 5 in this embodiment) of the specific user “Neo”. According to this embodiment, channel selecting information of each of the users comprises a favorite channel. For example, when the channel selecting information from the latest statistics of thedatabase 114 indicates the favorite channel of the user “Neo” ischannel 5, thechannel selecting module 118 accordingly learns that the favorite channel of the user “Neo” ischannel 5 and thus selectschannel 5. However, this example is disclosed to gain a better understanding of the present invention, and it shall not be construed as limiting the present invention. According to a variation of this embodiment, the channel selecting information of each user comprises a favorite channel or a plurality of favorite channels each having a priority. For example, when the channel selecting information from the latest statistics of thedatabase 114 indicates the favorite channels of the user “Neo” ischannel 5, channel10, channel15, and channel20 in sequence; thechannel selecting module 118 activates theTV receiver 110 to display the numbers of the favorite channels in the priority sequence so that the user can select one of the favorite channels. According to a variation of this embodiment, when a reply of the user is not obtained within a predetermined time, e.g., several seconds, thechannel selecting module 118 directly determines that a favorite channel having a highest priority, e.g.,channel 5, is the favorite channel. - In
Step 928, thechannel selecting module 118 selects a channel according to a common approach; however, this example is disclosed to gain a better understanding of the present invention, and it shall not be construed as limiting the present invention. According to a variation of this embodiment, thedatabase 114 further stores channel selecting information corresponding to a general user. Therefore, thechannel selecting module 118 selects a channel according to the channel selecting information corresponding to the general user. FIG. 3 is a flowchart of a TV control method in accordance with an embodiment of the present invention. More particularly,FIG. 3 is a flowchart of thecontrol flow 930 of theTV receiver 110, and this embodiment is a variation of the embodiment illustrated inFIG. 2 . According to this embodiment, channel selecting information of at least one user may further comprise one or more channel prohibited from viewing. For example, when the user “Neo” is the head of a family, he has an authority for defining theTV system 100, such as defining a prohibited channel with respect to each member of the family. In addition to defining a prohibited channel for an underage member, the user “Neo” may also define an unwished channel as a default prohibited channel for the entire family.- In
Step 932, theTV receiver 110 receives the wireless signal via thewireless module 112 to obtain the ID data of the specific user. - In Step934, the
user identification module 116 retrieves the channel selecting information corresponding to the specific user. More particularly, theuser identification module 116 retrieves the channel selecting information corresponding to the specific user from thedatabase 114 and provides the obtained channel selecting information to thechannel selecting module 118. For example, when the specific user is “Neo”, theuser identification module 116 searches thedatabase 114 for the ID data carried by the wireless signal, and accordingly retrieves the channel selecting information corresponding to the user “Neo”. - In
Step 936, after receiving the channel selecting information provided by theuser identification module 116, thechannel selecting module 118 learns whether the channel selecting information comprises prohibited channels. More particularly, after receiving the channel selecting information provided by theuser identification module 116, thechannel selecting module 118 learns whether the channel selecting information comprises a prohibited channel list. When the channel selecting information comprises prohibited channels, Step938-1 is performed; otherwise, Step938-2 is performed. For example, after Step934 of retrieving the channel selecting information corresponding to the user “Neo” by theuser identification module 116 and providing the channel selecting information to thechannel selecting module 118 is performed, thechannel selecting module 118 learns that the channel selecting information comprises prohibitedchannels 54 and55, and Step938-1 is to be performed. - In Step938-1, the
channel selecting module 118 selects a channel according to the channel selecting information and skips the prohibited channels during a channel switching. More particularly, when the user “Neo” activates theTV receiver 110 to select his favorite channels, under control of thechannel selecting module 118,Step 924 andStep 926 are performed. Once the user “Neo” switches channels one after another,channels 54 and55 are skipped. For example, when switching from channel40 and upwards, channel53 directly jumps to channel56 without going throughchannels 54 and55. When switching from channel70 and downwards, channel56 directly jumps to channel53 without going throughchannels 55 and54. - In Step938-2, the channel selecting module18 selects a channel according to the channel selecting information. For example, when the specific user activates the
TV receiver 110 via theremote controller 180 to select his favorite channels, under control of thechannel selecting module 118. Step924 andStep 926 are performed. Since no prohibited channel exists under this condition, once the specific user switches channels one after another, the channel is switched upwards and downwards in a normal numerical order.
